The following video podcasts are based on the Chemistry units found within the Ontario Curriculum

Rank #1: 3.04 - Polyatomic Ions - 14:06

Podcast cover
Read more
KEY TERMS: 2 or more non-metals, Nick the Camel ate a Clam for Supper in Phoenix, "ate" ending

Underlined letter represents the atom
# of consonants = # of oxygens
# of vowels = # of negative charges associated with polyatomic
Ending is "ate" - except for ammonium ion and hydroxide ion

5 Step Cross over rule:
- Remember that polyatomic has brackets and the charge is written outside of the brackets
- remove brackets when the number outside of the brackets is a "1"javascript:void(0)

Rank #3: 4.02 - Balancing Equations - 22:35

Podcast cover
Read more
KEY TERMS: balance both sides of the equation by placing a number (coefficient) in front of the compound. Don't be afraid to have to change that number if it does not completely balance the equation. Balance polyatomic ions first. Remember that REACTANTS are to the left of the arrow and PRODUCTS are to the right of the arrow. Refer to episode on "Counting Atoms". Don't forget your diatomic molecules:

oxygen = O2
hydrogen = H2
bromine = Br2
chlorine = Cl2
iodine = I2
fluorine = F2
nitrogen = N2

Rank #9: 3.06 - Acid Base Nomenclature - 14:48

Podcast cover
Read more
KEY CONCEPTS: When naming Binary Acids, start by identifying the hydrogen atom as "hydro" and name the non-metal using the "ic" ending and add the word acid.

Rules for Oxy-Acids:
They are derivatives of polyatomic ions and polyatomic variations. Follow the following 4 rules:

i.) ____ate ions become _______ic acid
ii.) per____ate ions become per_____ic acids
iii.) ____ite ions become _____ous acids
iv.) hypo____ite ions become hypo_____ous acids

Bases contain hydroxide ion (OH)-1

**NOTE: NO "hydro" for oxy-acids

Rank #10: 5.01 - Synthesis Reactions - 15:18

Podcast cover
Read more
KEY CONCEPTS:

2 or more reactant --> 1 product

metal oxide + water --> base (bases contain an OH-)

non-metal oxide + water --> oxy-acid
(oxy-acid is a polyatomic with a hydrogen acting as a cation) - see what type of polyatomic comes to mind when you look at the non-metal oxide

KEY CONCEPTS:

1 reactant --> 2 or more products

metal hydrogen carbonate --> metal carbonate + CO2 + H2O
(the metal can be any of the metals to the left of the aluminum ladder combined with a hydrogen carbonate. The end products are CO2 and H2O along with the metal bonded to the carbonate)

i.e: NaHSO4 --> Na2SO4 + CO2 + H2O

Rank #15: 5.03 - Single DIsplacement Reactions - 18:52

Podcast cover

KEY CONCEPTS:

metals switch with metals**
non-metals switch with non-metals

**look at the Activity Series if metal would switch with metal. If LONELY metal is higher in the Activity series than the metal paired with the non-metal can the metal switch places. If the LONELY metal is lower in the series, NO REACTION will take place.

Don't forget to balance equations! Don't forget the 5 Step Cross Over Rule
